Integrated Management of Bacterial Leaf Blight of Rice under Field Condition

Abstract: The present study was conducted on evaluation of different fungicides, antibiotics and antagonists against bacterial blight disease under field conditions. Among them, combi fungicide streptomycin sulphate 18.75 w/v + oxy tetracycline 2 w/v (200ppm)+ trifloxystrobin 25 + tebuconazole 50 (75WG) at 0.03 per cent was found significantly superior and most effective for the control of bacterial blight and recorded minimum disease intensity (26.28%), the highest grain yield (5.63 kg/plot), highest straw yield (7.08kg/plot) and the highest test grain weight (27.43g) which was statistically at par with streptomycin sulphate 18.75 w/v + oxy tetracycline 2 w/v (200ppm) + azoxystrobin 18.2 + difenconazole 11.4 SC at 0.03 per cent. Followed by streptomycin sulphate 90 w/v + tetracycline hydrochloride 10 w/v at 1000ppm and copper oxychloride 50 WP at 1.25 per cent, respectively.
